Patent FR-2523883-A1 (FR)
Inventor: STEPANENKO ALEXANDR VASILIEVIC
IPC: B22F9/04
Filed: 1983-03-23
Abstract: The method for manufacturing metal fibres from spherical particles (6) of a metal powder provides for feeding the spherical particles (6) of the metal powder to a main roll (2) and a supplementary roll (3) of a deforming tool (1) so that each of the spherical particles (6) is transferred in the direction of technological processing, deformed by rolling and is simultaneously extended along a rotation axis thereof. The extension of the particles is effected through a means, being the supplementary roll (3), at a rate which is higher than the rate of a free flow of the metal into an extension zone, which flow might occur whilst the diameter of the deformed spherical particle is reduced by said supplementary roll. Then the metal fibres are unloaded.

Title: Apparatus using a source of radiation to measure the wall thickness of pipes during manufacture
Inventor: MONNO ASAO
IPC: G01B15/02
Filed: 1983-08-02
Abstract: The apparatus comprises a source of radiation 21 formed by a row of sources of radiation and a detector 22 also in linear form. The radiation from the source passes through a collimator which shapes it into parallel beams. These pass transversely through the tubular component 11 whose wall thickness is to be determined. The length of the source 21 and the radiation detector 22 is greater than the diameter of the component 11 so that the radiation traverses the whole cross-section of the component. The mean wall thickness of the component may be determined from the attenuation recorded by the detector 22.
